Peter Jameson, managing engineer of the Dunsdale-based company, said doing the project in Chloe’s memory had been “a nice honour”.

The exact cause of Chloe’s death may never be known.

She was staying with her grandmother, Rosaline Goulding, in Rossett Walk, Park End when the tragedy happened.

The youngster had felt unwell before falling asleep. The next morning she was found to have died in her sleep.

An inquest into her death was told last July that Chloe suffered from hydrocephalus - a condition involving fluid build-up on the brain.

A Home Office pathologist said he was unable to identify the exact cause of death but felt it was in some way related to her condition. Teesside Coroner Michael Sheffield recorded a verdict of natural causes.

Tragically, since Chloe’s death, her dad Mark Goulding has also died.

Chloe’s mum said coping with the loss had been “very difficult”.

She has another daughter, Nicole, six, and two sons, Kian and Riley, four.

Gail is expecting another child, a boy, in June. She said: “I was happy when I found out I was pregnant.”
